mitted on the 400, 600, 900, 1500 and 2500 Lb. flange standards

but it must be added to the minimum flange thickness.

flange thickness dimensions.

3. A tolerance pf plus or minus 0.016 inch (1/64 inch) is allowed

on the inside and outside diameters of all facings.

4. Care should be taken in the use of joints of these dimensions,

(they apply particularly on lines where the joint is made on

the end of pipe) toinsure that pipe used is thick enough to

permit sufficient bearing surface to prevent crushing gasket.

Threaded companion flanges are furnished with plain face

and are threaded with American Standard Locknut Thread.

5. Gaskets for male -ffemale and tongue-groove joints shall coverthe bottom of the recess with minimum clearances taking into

account the tolerances prescribed in Note 3.
